  1. 1. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets

    Författare :Lukasz Michalak; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; master equation; magnetic nanoparticles; spin accumulation; molecular magnets; TMR; tunneling magnetoresistance; F-SET; ferromagnetic single-electron transistor; single-electron tunneling; nanomagnetism; spintronics; Coulomb blockade;

    Sammanfattning : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. LÄS MER

  3. 2. Kvalitet i banktjänster : privatkunders upplevda problem med banktjänster : en studie med hjälp av kritisk-händelse-metoden

    Författare :Morten J. S. Olsen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Tjänster; Marknadsföring;

    Sammanfattning : An important aspect of customer-perceived quality is what are termed critical incidents, i.e. incidents which diverge from what is intended or what is expected. The principal aim of the study is to create greater understanding of how private customers perceive critical incidents in banking services. LÄS MER

  4. 3. Towards Efficient Monte Carlo Calculations in Reactor Physics : Criticality, Kinetics and Burnup Problems

    Författare :Ignas Mickus; Jan Dufek; Andrea Zoia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kärnenergiteknik; Nuclear Engineering;

    Sammanfattning : This thesis presents a compilation of work focused on Monte Carlo crit-icality, kinetics and burnup calculations in reactor physics. Performing suchcalculations usually comes at a high computing cost. Therefore, the main mo-tivation behind the presented work is lowering the computing cost of MonteCarlo calculations. LÄS MER

  5. 4. Free Boundary Problems of Obstacle Type, a Numerical and Theoretical Study

    Författare :Mahmoudreza Bazarganzadeh; Henrik Shahgholian; John King; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Partial differential equations; Numerical analysis; Free boundary problems; Mathematics; Matematik;

    Sammanfattning : This thesis consists of five papers and it mainly addresses the theory and schemes to approximate the quadrature domains, QDs. The first deals with the uniqueness and some qualitative properties of the two QDs. The concept of two phase QDs, is more complicated than its one counterpart and consequently introduces significant and interesting open. LÄS MER

  7. 5. Constraint-Based Register Allocation and Instruction Scheduling

    Författare :Roberto Castañeda Lozano; Christian Schulte; Ingo Sander; Mats Carlsson; Laurent Michel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; constraint programming; combinatorial optimization; register allocation; instruction scheduling; compiler construction; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Register allocation (mapping variables to processor registers or memory) and instruction scheduling (reordering instructions to improve latency or throughput) are central compiler problems. This dissertation proposes a combinatorial optimization approach to these problems that delivers optimal solutions according to a model, captures trade-offs between conflicting decisions, accommodates processor-specific features, and handles different optimization criteria.
